There's a flicker across Black Bolt's face, something that might hardly register on the face of anyone else, but could be called a smile in the stern silence of Black Bolt's bearing. He'd liked this boy — the human whose name he never even learned. That earnest enthusiasm is rare, and a trait he's always enjoyed in people.

This also explains why he hadn't spotted Nux in his recent visit of the Compound. How long has he been out here, past its gates?

A few steps from his side as well draw the two of them together, and he holds out a hand. It looks like it could be an intended handshake, but when he's close enough he goes to grip Nux's forearm, not his hand, for a familiar greeting. And why not? Everyone here is a stranger, but it's good to see a stranger he'd liked.
